Futaba R70SR FASSTest 2.4GHz Backup Receiver
The Futaba R70SR adds a lightweight backup RF reception path to compatible Futaba Dual Rx Link systems. Its slim housing fits installations with limited space, while dual antenna diversity provides reception through two antennas. Weighing just 0.14 oz (3.9 g), the R70SR adds backup reception with minimal additional weight.
Designed for Dual Rx Link Backup Use
The R70SR works alongside compatible Futaba receiving equipment. It cannot operate servos directly and does not transmit telemetry. A compatible main receiver or supported unit and a female-to-female connection cable are required. The connection cable is sold separately.
